Whatever items you end up picking, make them "one-bite" pieces. Your guests will appreciate not having half of something squirt down the front of the good clothes as they try to bite into a big canapé !

Here is my recipe for pork bulgogi that would be super portable for a stand up dinner and they are affordable and easy! https://food52.com/recipes/36459-pork-bulgogi-yakitori
